Welded Hydraulic Oil Cylinder

Welded Hydraulic Oil Cylinder

The Oil Cylinder is made of cast iron, and j506 welding requires hot welding process. It is welded after preheating and heat preservation after welding. However, it is difficult to have such welding conditions in actual maintenance, otherwise it is easy to produce small cracks and tear them again during use.

To fundamentally solve this problem, the first welding must be successful, and no welding cracks should be produced. After welding, it is better to carry out dye detection. If there are obvious cracks in the detection, they should be removed at that time

Generally, such leakage needs to be repaired by cold welding process. During the welding process, the welding temperature should be kept at room temperature at all times, and we777 special cast iron electrode with good crack resistance should be selected as the welding material. Many good welders fail in the selection of welding material. J506 has poor ductility for cast iron, and hot welding process is not used, so cracks are produced Natural.
